The Effect of Teacher Candidates’ Science Process Skill on Analytical Chemistry Through Guided Inquiry Learning Model

Abstract

Abstract This study was purposed to find out is there any significant difference of guided inquiry and conventional learning model implementation towards Analytical Chemistry practicum courses, particularly on Redox, Argentometry and Complexometry titrations. This study also analyzed the effect of the learning model through quasi-experimental method. There were 28 teacher candidates in experimental class which taught by using guided inquiry (GI) learning model and 23 teacher candidates in control class which taught by using conventional learning model. Based on Mann-Whitney test, p-values for Redox, Argentometry and Complexometry practicum courses were 0.001, 0.012, 0.030 respectively. Since p-values were less than 0.05 then Ha is accepted which means teacher candidates’ science process skill in experimental class is different significantly compared to control class. The effect of model was calculated through N-gain which score 81%, 76% and 80% in experimental class and 55%, 57% and 59% in control class for respective practicum. This means the teacher candidates’ science process skill is better in experimental class (taught by using GI model) than control class (taught by using conventional model). These findings give contribution to chemistry education especially for improving chemistry teacher candidates’ quality and reducing them who often feel difficult to learn Analytical Chemistry.
